These are some of the experiences people from different parts of the world have been sharing online.

"BEN", TEHRAN

"Ben" is a student and he lives with his family in western Tehran. He has been twittering and is constantly resending, updating and gathering information from other users.

"Fortunately all my exams have been postponed for a couple of weeks, so I have dedicated myself to informing the world about the situation in Iran. I haven't seen my girl since the election queues.

I have many active and trusted friends, which I call in regular basis (when I can) to get information. Sometimes I go out by myself.

Other twitterers are another good source as well; you can learn to trust the right people and re-tweet or confirm based on their tweets. The websites follow a similar rule too. I know who I can trust, and who I can't.

I have received a lot of support from foreign friends, especially from Toronto, Canada.

Before the elections, I worked with others on a website. This was our first go at getting online support for the election.

After the announcement of results, I had to continue updating as an anonymous twitterer. I don't have any experience in journalism and this is my first real experience.

I do have friends with some journalistic background, from which I get some hints everyday. But the main idea these days are to be creative, because almost all of this situation had been calculated by the current government, so we try to do something new."

MIKE KLAMBRO, SPAIN

Speaking nine languages, Mike manages to follow many global news stories online via a combination of mainstream stations and a depth of knowledge applied when reading from social media websites. He has been active in following and spreading news links on Twitter as @Advorec

Mike Klambro reads citizen updates from inside Iran

"The connection out of Iran is very slow at the moment so when people upload videos it can be up to an hour later.

Following Twitter provides a lot of links and videos from Tehran, but it also has its problems. Some things are being lost in their translation to English and they are coming across as more harsh than they were meant in the original.

On Twitter you only have 140 characters to create a message, so people need to read between the lines correctly. Those who are using Twitter in Tehran are educated enough to add things to show if information has been confirmed or is unconfirmed, but you have a limited space to do this.

The videos on YouTube difficult to link to a particular news story because they show so much but there are no details.

There is a difference this time in that message being spread as opposed to a similar idea back in 1979. It has been reported that Mousavi may be under house arrest. This is what happened last time, the opposition was rounded up and either put under house arrest or taken to prison. This time communications mean that messages can be sent out via mobile phones or online.

There is a certain amount of fear surrounding information out of Iran but the actions in Iran ironically make things more difficulty for the authorities.

People are able to work out proxies relatively easily to get around SMS messages or access to Twitter being blocked. To enable these proxies the user becomes anonymous and untraceable, more than if they had normal access, so if authorities were looking to find these people, they are making it harder for themselves."

BEHDAD ESFAHBOD, TORONTO, CANADA

Behdad is a software engineer. He was born in Iran and has lived in Canada since 2003. He has been posting various links to information coming from Iran on his personal blog.

Behdad Esfahbo sifts through the information coming from Iran

"Me and a group of friends here in Canada are creating a timeline of events and sifting through all the information coming out of Iran.

We are following events on websites, Facebook and Twitter. But you have to be careful and look at the sources of information. It is better if you know what different websites are associated with. Some false information has been spread by people who mean well.

As they have shut down mobile phones and Facebook, and the internet is very slow in Iran, some people have resorted to using email as the main form of communication.

There is a newsletter that is sent every few hours with inside news and schedule of the protests.

I started writing in my blog about the election results because I realised many people in Iran didn't know what was going on. I Phone some friends and relatives and they didn't know. Some people actually believe the vote count was real, and I want to help them see some of the facts."
